With time-varying adverse selection in the market for new equityissues, firms will prefer to issue equity when the market ismost informed about the quality of the firm. This implies thatequity issues tend to follow credible information releases.In addition, if the asymmetric in information increases overtime between information releases, the price drop at the announcementof an equity issue should increase in the time since the lastinformation release. Using earning releases as a proxy for informativeevents, we find evidence supporting these propositions. 相似文献

Economic Perspectives on Health Information Technology 总被引:1,自引:0,他引:1
David J Brailer 《Business Economics》2005,40(3):6-14
It seems paradoxical that health care spending and
examples of inferior health care have been rising rapidly
at the same time. An important factor is the slow
pace at which the health care system has adopted information
technology (IT). This paper discusses the dimensions
of the problems that could be mitigated by effective
use of IT in the health care system, their consequences,
and their potential solutions. It also discusses
the economic and institutional barriers to deploying IT and how the inherent economies of scale in IT are likely
to lead to new problems of competition within the health
care system. Inasmuch as this paper was based on an
address followed by a question-and-answer period, it
also includes an edited version of the recorded questions
and answers.JEL Classification I180, I190 相似文献

ABSTRACTYears ago, a small handful of leisure scholars suggested that serial murder may be a form of leisure. However, to date this possibility remains virtually unexplored. This article draws from recent research to share reflections and rich, new insights on how leisure science may provide important contributions to serial homicide researchers and law enforcement personnel. At the same time, exploring such intersections offers leisure scholars new ways of understanding familiar concepts and theories. Possibilities for future research are discussed. 相似文献

I investigate the empirical importance of information revelationin the pricing of block trades. In particular, I examine whetherblock prices are correlated with the unexpected part of firms'quarterly earnings. For my sample of block trades, informationrevelation does indeed appear to be a significant factor shortlybefore earnings announcements. 相似文献

This paper challenges what is the standard account of UK employment,namely that the major swings in unemployment over the past 25years are due predominantly to movements in the underlying empiricalnatural rate of unemployment (NRU). Our analysis suggests thatthe UK NRU has remained reasonably stable through time and thatthe medium-run swings in unemployment are due, instead, to veryprolonged after-effects of persistent (transitory but long-lasting)shocks. We argue that (i) past UK labour market shocks haveprolonged after-effects on unemployment due to interactionsamong different lagged adjustment processes in the labour market;(ii) many of the important shocks that have hit the UK labourmarket over the past 25 years have been persistent; and (iii)the persistence of the shocks is complementary to the persistenceof the lagged adjustment processes in generating movements ofUK employment. 相似文献

The change of government in South Africa and the subsequent implementation of the Reconstruction and Development Programme (RDP) has necessitated afresh look at the spatial‐economic development policies of the past. Recently, an attempt was made to measure differences in existence level in South Africa using a combination of First and Third World criteria. In this paper these differences are related to general trends in population redistribution in the country since 1960 in an effort to assess the probable impact of existence level difference and migration on urbanisation in South Africa in the long run. On the basis of these assessments, expected trends in urban development in South Africa are compared with previous industrial development policies in an effort to determine RDP imperatives for the future. 相似文献

The 1997 collapse of the Albanian economy caused by the collapseof economy-wide Ponzi schemes contrasts sharply to its successstatus as a post-Socialist transition country in the years 1992-1996.In this paper, an attempt is made to explain this 'AlbanianParadox'. The specific Albanian conditions for the growth ofPonzi schemes are identified. Theoretically, the Albanian Paradoxcan be interpreted as one version of the 'Financial InstabilityHypothesis' suggested by Minsky. Investigation of the underlyingfactors that render financial markets fragile suggest that theAlbanian case is extreme but not unique in the region. It isemphasised that sustainable growth is predicted on the qualityof government, on proper financial-sector regulation, on actualmicroeconomic restructuring and on the development of marketinstitutions through which adequate market information is disseminated. 相似文献

Business leaders continue to blame the skyrocketing cost of health care for jeopardizing the global competitiveness of U.S. industries, and they continue to turn to Washington for the solution. Yet after a study of 16 countries, Wharton researchers David Brailer and R. Lawrence Van Horn have discovered that health care costs do not directly hinder U.S. competitiveness. Their conclusion: there is indeed a health care crisis in the United States as well as a competitiveness crisis. But the two are unrelated, and confusing them makes it difficult to solve either one. The real problem, according to the authors, is the hands-off approach that employers typically adopt when it comes to health care. No matter how Washington responds to the health care crisis, employers must explore their own role in ensuring the health of their work force. And they must realize that their role can be a strategic one. Instead of containing costs by fine-tuning benefits packages, companies can control costs and improve health care delivery by treating health care like any other crucial component of production. Brailer and Van Horn propose three strategies for managing health care delivery: First, companies must intervene in the supply side of the health care market. This may mean creating a clinic alone or with other companies, or joining with other companies to procure health care. Second, companies need to translate corporate health benefits into the most cost-effective set of services at the local level. Finally, companies must encourage and educate employees to participate in decisions regarding health care delivery.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Liquidity provision with limit orders and a strategic specialist 总被引:12,自引:0,他引:12
This article presents a microstructure model of liquidity provisionin which a specialist with market power competes against a competitivelimit order book. General solutions, comparative statics andexamples are provided first with un-informative orders and thenwhen order flows are informative. The model is also used toaddress two optimal market design issues. The first is the effectof 'tick' size - for example, eighths versus decimal pricing- on market liquidity. Institutions trading large blocks havea larger optimal tick size than small retail investors, butboth prefer a tick size strictly greater than zero. Second,a hybrid specialist/limit order market (like the NYSE) providesbetter liquidity to small retail and institutional trades, buta pure limit order market (like the Paris Bourse) may offerbetter liquidity on mid-size orders. 相似文献
